A device connected to the Internet (for example, your computer, router in fact) has a unique address; A so-called IP address. This IP address is similar to your home address, a unique description of your home location, allowing others to find them. This IP address is required, because you cannot access the internet without it. Without IP addresses, other computers and websites do not know where to send the requested information (for example, a YouTube video).
The disadvantage of having a unique IP address is that everything you do on the web (viewing websites, viewing videos, sending email, downloading, etc.) is related to your environment. This, of course, is a major violation of your privacy. With a VPN, all your Internet traffic is routed through a (chosen by you) server, so other people, websites, and agencies only see the IP address and location of the VPN server.
Your own IP address and location will remain hidden.
Use secure (public) networks
With the increase in the use of mobile devices with the Internet (laptop, tablet, smartphone), there is much more work out of home or home. More and more airports, cafés and hotels provide access to their network with internet connection, often free. But unfortunately there are disadvantages.
The disadvantage of using these public networks is the major security risk you are facing. Simply put, every person in this network can easily intercept, read and even adjust all your Internet traffic. This may allow them to plunder your bank account, hack your email or Facebook and steal your personal information. It is important to realize that this fact is not a theoretical danger, but a method that criminals increasingly use.
A VPN encrypts all your Internet traffic on your computer, so someone else cannot read it and cannot manipulate it.
Netflix, HULU, VEVO, BBC iPlayer
Many well-known online video services are regionally bound. This means that they cannot be viewed from a country other than where they have contracts with the film industry. Examples include Netflix, HULU, VEVO and BBC iPlayer. If you are in the USA, you can (often free) use these services, but you do not live in America, then you will not. To bypass these location-related limitations, you can use a VPN. You then connect to a server in the streaming service country (e.g. America). From then on all your internet traffic will be routed through this server and the video service will think you are in that country and you can use these services.
